Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is renowned for its extensive range of applications, attributed to its adaptability and cost-effectiveness compared to other advanced ceramics. Alumina provides excellent electrical insulation resistance, withstands high temperatures, exhibits robust hardness, and offers superior wear and chemical resistance, making it the ideal choice for challenging environments involving high temperatures and corrosive chemicals.
Our manufacturing facility specializes in alumina parts with purity levels from 75% to 99.8%. All ceramic parts are crafted with a dense body through advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To meet unique application needs such as fitting, friction reduction, and insulation enhancement, we offer secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
We produce a diverse selection of alumina ceramic rings, spanning ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you require prototypes or large production runs, we are fully equipped to provide solutions tailored to your specific requirements.
